2003–2010年千烟洲人工针叶林碳水通量观测数据集

全球变化背景下陆地生态系统碳水循环过程、控制机理及其对环境变化的响应是生态学与全球变化科学长期致力解决的重大科学问题。涡度相关技术是原位、连续、高频观测生态系统碳水交换过程的强有力技术途径。千烟洲站作为国内首批建立涡度相关观测系统的野外台站，已经持续积累了17年的人工针叶林生态系统碳水交换通量的科学观测数据。为了推动中国乃至全球陆地生态系统通量研究及相关领域的发展，千烟洲站公开发表了整理加工的2003-2010年连续观测的碳水通量及相关气象要素数据。本数据集包含生态系统总初级生产力、生态系统呼吸、净生态系统生产力、潜热通量、显热通量、空气温度、空气相对湿度、水汽压、风速、风向、土壤温度、土壤水分、太阳辐射、光合有效辐射和降水等观测指标，形成了半小时、日、月和年尺度数据产品。

Against the backdrop of global change, the carbon and water cycling processes, underlying control mechanisms and their responses to environmental changes in terrestrial ecosystems are long-standing major scientific issues that the fields of ecology and global change science have long been committed to solving. Eddy covariance technique is a powerful and robust approach for in-situ, continuous and high-frequency observations of carbon and water exchange processes in ecosystems. As one of the first domestic field stations to establish eddy covariance observation systems, Qianyanzhou Station has accumulated 17 consecutive years of scientific observation data on carbon and water exchange fluxes in planted coniferous forest ecosystems. To promote the development of terrestrial ecosystem flux research and related fields in China and even globally, Qianyanzhou Station has publicly released processed and curated carbon and water flux data and related meteorological element data from continuous observations conducted between 2003 and 2010. This dataset includes observed indicators such as gross primary productivity (GPP), ecosystem respiration, net ecosystem productivity (NEP), latent heat flux, sensible heat flux, air temperature, air relative humidity, water vapor pressure, wind speed, wind direction, soil temperature, soil moisture, solar radiation, photosynthetically active radiation (PAR) and precipitation, and has created data products at half-hourly, daily, monthly and annual temporal scales.
